Haber process:
- The Haber process is the process of synthesis of ammonia gas by reacting together hydrogen gas and nitrogen gas in a particular stoichiometric ratio by volumes and at selected optimum temperature and pressure.
- The chemical reaction is:
The reaction proceeds with a decrease in number of moles (Δn = -2) and the forward reaction is exothermic.
- Iron (containing a small quantity of molybdenum) is used as catalyst.
- The optimum temperature is about 773 K and the optimum pressure is about 250 atm.
